The slope of the line is

(9-5) / (4- -2) = 4/6 = 2/3 .


If the x-intercept is -2 and the y-intercept is 1, then the equation of the line is

y = 1/2 x + 1 .

None of the choices is correct.

Answer:

440cm³

Step-by-step explanation:

Area of trapezium base=

\frac{1}{2} \times (a + b) \times h

\frac{1}{2} \times (8 + 14) \times 4

\frac{1}{2} \times 22 \times 4 \\  =  \frac{88}{2}  \\  = 44 {cm}^{3}

Volume=Area or trapezium x Height between trapezium ends

= 44 \times 10 \\  = 440 {cm}^{3}

Need geometry help ASAP please!

Answer:

1. 121 π  unit²

2. 143°

3. 151 unit²

Step-by-step explanation:

1.

Area of a circle is given by the formula  A = πr²

where

A is the area,

r is the radius of the circle

From the given diagram, we can see that the radius is 11, hence the area will be:

A=\pi r^2\\A=\pi (11)^2\\A=121\pi

The answer is  121\pi units^2

2.

The unshaded secctor and the shaded sector equals the circle. We know that circle is 360°. The unshaded sector has an angle of 217°. So the shaded part will be 360 - 217 = 143°

The measure of the central angle of the shaded sector is 143°

3.

Area of a sector is given by the formula  A=\frac{\theta}{360}*\pi r^2

Where

\theta is the central angle of the sector (in our case it is 143°)

r is the radius (which is 11)

Plugging in all the info into the formula we have:

A=\frac{\theta}{360}*\pi r^2\\A=\frac{143}{360}*\pi (11)^2\\A=150.99

<em>rounding to the nearest whole number, it is </em>151 units^2
